Search for missing Yosemite hiker scaled back

YOSEMITE NATIONAL PARK -- Rescue crews are scaling back their weeklong search in Yosemite National Park for a Southern California man who went out on a day hike and never came back.

Park officials announced Thursday that rescue crews will now focus on a limited search in the area George Penca (pen-sa) was last seen. Officials said park rangers have not found any clues to Penca's whereabouts.

The 30-year-old Hawthorne man was last seen Friday as he hiked the Upper Yosemite Fall trail in Yosemite Valley with about 20 people from his church. When the church members finished their hike, Penca was not with them.

About 105 search and rescue personnel from around the state have participated in the search. Park officials say the trail that Penca disappeared on was popular and well-maintained.
